Horizontal intermediate check valves shall be installed in the run of each riser continuing into a higher zone in such manner as to permit all upper zones of the system within each two-way Fire Department connection zone provided in accordance with section 4.8.2.2 to be fed through one riser from the zone below and to prevent any lower zone of the system from being supplied from a zone above, except as otherwise required by this referenced standard. Two-way Fire Department connection zones shall be interconnected as in accordance with Section 4.8.2.2(j).

(6) Each two-way Fire Department connection shall be connected to a riser or to a cross connection connecting other two-way Fire Department hose connections or risers within each two-way Fire Department zone provided in accordance with section 4.8.2.2. The pipe from the two-way Fire Department connection to the riser or cross connection shall be five inch (123 mm) I.P.S., except that a 4 inch (102 mm) pipe shall be sufficient when such pipe supplies a single four inch (102 mm) riser system. The pipe from the two-way Fire Department connection shall be run as directly as practicable to the riser or cross connection.

(7) When tanks are used for the primary water supply, the standpipe systems may use separate riser systems serving, respectively, low and high parts of the building. Separate gravity tanks or pressure tanks may supply each zone, but in every case the standpipe system shall be so designed that every hose outlet of the entire system can be supplied through the required cross connections from every two-way Fire Department connection within each two-way Fire Department connection zone provided in accordance with section 4.8.2.2.

Delivered Audio Quality (DAQ). A measure of audio quality over a transmission medium as defined in standards published in TIA/TSB-88C. The following table shows the DAQ descriptions as published in the document:

Delivered
Audio
Quality
(DAQ)


Faded Subjective Performance Description
1 Unusable, speech present but unreadable
2 Understandable with considerable effort. Frequent repetition due to noise / distortion.
3 Speech understandable with slight effort. Occasional repetition required due to noise /
distortion.
3.4 Speech understandable with repetition only rarely required. Some noise / distortion.
4 Speech easily understood. Occasional noise / distortion.
4.5 Speech easily understood. Infrequent noise / distortion.
5 Speech easily understood.

Dedicated Radio Console (DRC). A fixed location console that contains at least the following components:

(1) A handset or headset to broadcast and/or receive voice communications from/to ARCS.
(2) A visual display to identify all signals transmitted from the Firefighter handheld units and supervisory signals.
(3) Fire Department city wide standard key (#2642) to enable/disable radio transmission.

In-Building Auxiliary Radio Communication System (ARCS). Wireless two-way radio communication enhancement system installed in buildings to propagate Fire Department wireless frequencies for the use of the Fire Department in case of an emergency.

Repeater Channel System.
A repeater system utilizing channels with paired receive and transmit frequencies. When a user within the building transmits on a repeater channel, the repeater system rebroadcasts the users’ signal to the DRC and all users within the building on that channel. This transmission increases the distance from which users can directly talk with each other. A user at the DRC must enable repeater channel for users to communicate.

Simplex Channel System.
A simplex system utilizing channels with the same frequencies for transmit and receive. Users communicate on simplex channels radio-to-radio without going through infrastructure. However, their radios need to be within a certain distance to be picked up by one another. A simplex system allows a user at the DRC to communicate with a user on a simplex channel anywhere in the building, even though the distance between the DRC and the user would typically
be prohibitive. A simplex system only extends the transmission’s reach for the DRC. It does not improve coverage between individual user radios.
